Remove PREPARE_VERSION and PREPARE_VERSION_KNOW
...
This patch removes the PREPARE_VERSION and PREPARE_VERSION_KNOW macro
and uses a static inline function instead, get_vdso_symbol. Each
architecture that supports vDSO must define the Linux version and its
hash for symbol resolution (VDSO_NAME and VDSO_HASH macro respectively).
It also organizes the HAVE_*_VSYSCALL for mips, powerpc, and s390 to
define them on a common header.
The idea is to require less code to configure and enable vDSO support
for newer ports. No semantic changes are expected.
Checked with a build against all affected architectures.
